Scientists have never been so worried about the state of the planet in general, and the climate crisis in particular. In one extensive call published Monday, November 5 in the journal BioScience, more than 11 000 climatologists but also biologists, physicists, chemists or agronomists, from 153 countries (including 1500 French), warn that humans risk "Indescribable suffering" related to the climate emergency. They call for global transformations of our ways of life to preserve life on Earth, "Our only home".

Exactly forty years ago, in 1979, the authors, led by biologist William Ripple (University of Oregon, USA), researchers from fifty countries gathered at the first world conference on climate in Geneva and warned of the need to act against climate change. Since then, warnings have proliferated at the Rio Earth Summit in 1992, the adoption of the Paris Agreement in 2015 or in the many reports of the Intergovernmental Panel on Climate Change. climate change (IPCC). In 2017, the magazine BioScience had also published a manifesto of 15,000 scientists, still on the initiative of William Ripple, who warned of the catastrophic degradation of the environment and the living world.

Nevertheless, greenhouse gas emissions have continued their inexorable progression and have brought with them a series of deleterious consequences for the climate, the environment and society, whether it concerns the rise in temperature , sea level rise, ocean acidification or melting glaciers.

"We have dedicated a new call to climate change only, because the latest scientific studies show that the climate crisis is accelerating more than we expected", explains William Moomaw, professor of international environmental policy at Tufts University, Massachusetts. "Deaths and diseases are increasing rapidly; whole industries and economies are threatened, especially in the poorest regions of the world "he continues.
